ifconfig -d is correct
ifconfig
Configure network interface parameters
Syntax:
ifconfig interface address_family [address [dest_address]]
[parameters]
ifconfig [-hLmvz] interface [protocol_family]
ifconfig -a [-bdhLmsuvz] [protocol_family]
ifconfig -l [-b] [-d] [-u] [-s]
ifconfig -s interface
ifconfig -C
Runs on:
Neutrino
Options:
-a
Display information about all of the interfaces in the system. You can use the -d, -u, -b, and -s options with this option to limit this display.
-b
List only the broadcast interfaces.
-C
List all of the interface cloners available on the system, with no additional information. This option is mutually exclusive with all other options and commands.
-d
List only the interfaces that are down.
-h
If you use this option in conjunction with -v, ifconfig prints the byte statistics are in human-readable format.
-L
Display the address lifetime for IPv6 addresses, as a time offset string.
-l
List all available interfaces on the system, with no additional information. This option is mutually exclusive with all other options and commands, except for -b, -d, -s, -u.
-m
Display all of the supported media for all of the interfaces in the system (used in conjunction with -a).
If you specify the -m option before an interface name, ifconfig displays all of the supported media for the specified interface.
-s
If you specify the -a option, the -s option makes ifconfig list only the interfaces that are connected.
If you specify the -s option for a specific interface, ifconfig queries the interface for its media status. If the interface supports reporting media status, and it reports that it doesn’t appear to be connected to a network, ifconfig exits with status of 1 (false); otherwise, it exits with zero (true). Not all interface drivers support media status reporting.
-u
List only the interfaces which are up.
-v
Print statistics on packets sent and received on the given interface. You can use the -h in conjunction with -v to display the byte statistics in human-readable format.
-z
